9 The DTSC-50 generator set controller provides the following functions: Genset control Engine and generator protection Engine data measurement - o including battery voltage, service hours, etc. Generator voltage measurement Alarm display with circuit breaker trip and engine shutdown AMF (automatic mains failure) standby genset control with automatic engine start on a mains failure detection and open transition breaker control Password protected configuration Intended Use The control unit must only be operated as described in this manual. The prerequisite for a proper and safe operation of the product is correct transportation, storage, and installation as well as careful operation and maintenance. NOTE This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions, configuration screens and other details described, which do not exist on your unit may be ignored. The present manual has been prepared to enable the installation and commissioning of the unit. Because of the large variety of parameter settings, it is not possible to cover every possible combination. The manual is therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings can be taken from the enclosed list of parameters. Woodward Page 9/106

10 Chapter 2. DTSC-50 Overview NOTE Some parameters of the DTSC-50 can only be configured using the Direct Configuration Cable DPC (P/N ) and a notebook/pc with the software eopc1. These parameters are indicated with an in the parameter description under Parameters starting from page 52 and can not be configured at the unit directly. The configuration with eopc1 via the DPC is described under Configuration Using the PC on page 50. The DPC is not part of the DTSC-50 shipment and sold separately (P/N ). IMPORTANT NOTE ABOUT COUNTERS The counters for Operation hours Maintenance Interval Number of starts can be recalibrated with eopc1 and the configuration files belonging to the unit. If 3 rd party users are not allowed to change these values, you can easily remove the parameters which enable changing the counters by editing the eopc1 configuration files as described under Editing the Configuration File on page 51. The counter for Maintenance Interval can also be recalibrated using the front panel. You may prevent the user from recalibrating this parameter by setting a HMI password as described under Codes on page 74. Page 10/106 Woodward

11 Chapter 3. Electrostatic Discharge Awareness All electronic equipment is static-sensitive, some components more than others. To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges. Follow these precautions when working with or near the control. 1. Before performing maintenance on the electronic control, discharge the static electricity on your body to ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.). 2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges as much as synthetics. 3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the control, the modules, and the work area as much as possible. 4. Opening the control cover may void the unit warranty. Do not remove the Printed Circuit Board (PCB) from the control cabinet unless absolutely necessary. If you must remove the PCB from the control cabinet, follow these precautions: Ensure that the device is completely de-energized (all connectors must be disconnected). Do not touch any part of the PCB except the edges. Do not touch the electrical conductors, connectors, or components with conductive devices with your hands. When replacing a PCB, keep the new PCB in the protective antistatic bag it comes in until you are ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the protective antistatic bag. CAUTION To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed Circuit Boards, and Modules. NOTE The unit is capable to withstand an electrostatic powder coating process with a voltage of up to 85 kv and a current of up to 40 µa. Woodward Page 11/106

Panel cut-out Cut out the panel according to the dimensions in Figure Remove terminals oosen the wire connection terminal screws on the back of the unit and remove the wire connection terminal strips if required (1) oosen clamping screws oosen the four clamping screws (1) until they are almost flush with the clamp inserts and tilt the clamp inserts down by 45 (2) to remove them from the housing. Do not completely remove the screws from the clamp inserts Insert unit into cut-out Insert the unit into the panel cut-out. Verify that the unit fits correctly in the cut-out. If the panel cut-out is not big enough, enlarge it accordingly. Ensure that the gasket is placed properly if used. Ensure that the paper strip is not pinched between gasket and panel to maintain isolation. 5. Attach clamp inserts Re-install the clamp inserts by tilting the insert to a 45 angle (1). Insert the nose of the insert into the slot on the side of the housing. Raise the clamp insert so that it is parallel to the control panel (2) Tighten clamping screws Tighten the clamping screws (1) until the control unit is secured to the control panel (2). Over tightening of these screws may result in the clamp inserts or the housing breaking. Do not exceed the recommended tightening torque of 0.1 Nm Reattach terminals Reattach the wire connection terminal strips (1) and secure them with the side screws. 1 Note: If the gasket is damaged, it needs to be replaced. Use only the original gasket kit (P/N ) for replacement. Woodward Page 13/106

17 Voltage Measuring The DTSC-50 allows the use of different voltage measuring methods for generator and mains voltage depending on the model. These are described in the following text. Measuring method 3Ph 4W 3Ph 3W 1Ph 2W 1Ph 3W Description Measurement is performed phase-neutral (WYE connected system). Phase voltages and neutral conductor must be connected for proper calculation. The measurement, display and protection are adjusted according to the rules for WYE or delta connected systems. Monitoring refers to the following voltages: V 12, V 23, and V 31, or V 1N, V 2N, and V 3N. Measurement is performed phase-phase (delta connected system). Phase voltages must be connected for proper calculation. The measurement, display and protection are adjusted according to the rules for delta connected systems. Monitoring refers to the following voltages: V 12, V 23, V 31. Measurement is performed for single-phase systems. The measurement, display and protection are adjusted according to the rules for single-phase systems. Monitoring refers to the following voltages: V 1N. Measurement is performed for single-phase systems. The measurement, display and protection are adjusted according to the rules for single-phase systems. Monitoring refers to the following voltages: V 1N, V 3N. Table 6-2: Voltage measuring principles The above described voltage measuring methods are shown with appropriate wiring examples for the different models for generator and mains voltage measuring in Figure 6-3 to Figure NOTE eopc1 and a DPC cable (Revision B, P/N ) are required to configure the voltage measuring methods 1Ph2W, 1Ph3W, 3Ph3W and 3Ph4W Woodward Page 17/106

27 Chapter 7. Operation and Navigation Figure 7-1: Front panel and display Figure 7-1 illustrates the front panel/display which includes push-buttons, EDs and the alphanumerical 7 segment ED display. A short description of the front panel is given below. NOTE This push-button is AWAYS enabled and will stop the engine when pressed Push-buttons The push buttons on the front panel are assigned to fixed functions of the unit EDs The EDs indicate operating states of the unit and alarm messages. The right ED indicates that alarm messages are present in the unit segment ED display This alphanumerical display is used to display all measured values, operating parameters, and alarm messages. A description of this display is detailed later in this manual. Woodward Page 27/106

28 Purpose of the Status EDs Page 28/106 Operation and Display The DTSC-50 has several status EDs to indicate the operating state. The EDs indicate the following conditions: ED 9 (on): Mains voltage present ED 9 (flashing): Mains voltage and/or frequency are not within the (see page 47) ED 10 : Mains circuit breaker (MCB) closed ED 11 : Generator circuit breaker (GCB) closed ED 12 (on): Generator in operation ED 12 (flashing): Generator voltage and/or frequency are not within the (see page 47) ED 13 (on): Engine in operation ED 13 (flashing): Engine in operation, but engine monitoring delay time (see page 55) not yet expired ED 14 : Alarm message present ED 15 : DTSC-50 in automatic operation mode ED 16 : DTSC-50 in manual operation mode ED 17 : DTSC-50 in stop operation mode A function test of all EDs and the seven-segment display may be conducted by pressing the 7 and 8 buttons simultaneously. Operating the DTSC-50 When the DTSC-50 control unit is powered up and the genset is not operating, ED 17 is illuminated and the MCB is closed The control unit may be started in automatic mode or have the operation mode changed from automatic to manual by pressing the Auto - Manual button 3. ED 15 (automatic) or ED 16 (manual) will indicate the current mode of operation by the corresponding ED being illuminated. The Breaker Control button 4 enables the operator to open or close the circuit breaker(s) depending on the current state of the breaker and the control unit being in manual operation mode. This button is disabled in automatic operation mode. The Start Engine button 5 will start the engine when the control unit is in manual operation mode. This button is disabled when the control unit is in automatic operation mode. The Stop button 6 is only enabled if Manual Mode or Automatic mode is NOT selected via the discrete inputs ( Terminals 16 and 17 ).If it is pressed while in automatic mode the engine will be shut down after the configured cool down period has expired. Pressing this button twice will shutdown the genset immediately. Active alarm messages may be acknowledged with the Alarm button 2. Alarm conditions are indicated when ED 14 is illuminated. When the DTSC-50 is in normal operation, the operator may view the monitored parameters by using the Scroll button 1. The monitored values will be displayed on the 7-segment display 18 (a detailed description of the displayed operating values may be found later in this manual). Acknowledging Alarm Messages ED 14 will flash when an alarm is active. The alarm message will be displayed in the 7-segment display 18. Pressing the alarm button 2 will acknowledge the alarm, reset the alarm relay (if relay is configured for alarm input), and the ED will change from flashing to continuously illuminated. If more than one fault condition is present, the operator may display these messages by pressing the Scroll button 1. The alarm may be deleted by pressing and holding the Alarm button 2 a second time until the ED 14 is no longer illuminated. If the fault condition is still present, the ED 14 will remain illuminated and the unit stays in a locked mode according to the appropriate alarm condition. Woodward

29 Configuring the DTSC-50 To enter the configuration mode, press the Scroll 1 and Alarm 2 buttons simultaneously. Only the parameters 00 - HMI Password, 01 - Time until horn reset and 72 - Display level are visible without entering a password. In order to display the other parameters, the correct password must be entered in the Parameter 00 - HMI Password. Pressing the Scroll button 1 will display the various parameters that may be changed. The displayed values for the parameters may be changed by pressing the 7 and 8 buttons (a detailed description of the parameters begins on page 52 of this manual). If the operator presses and holds these buttons, the rate of change for the value will increase. After the parameter has been adjusted to the desired value, enter it into the control unit by pressing the Scroll button 1 once. After a parameter has been changed and entered into the control unit, the operator may advance to the next parameters by pressing the Scroll button 1 a second time. To exit the configuration mode, press the Scroll 1 and Alarm 2 buttons simultaneously again. Display of the Operating Values You may advance through the single value displays using the Scroll button 1. The values are displayed numerically, while the engineering unit, source, and phase are coded in the sevensegment display 18 if applicable. See the example below: No. of transfers to Gen. Mains Generator Phase 4 digit value display Decimal point Figure 7-2: 6 digit 7 segment ED display The first digit (counted from left) indicates what is being measured, (mains, ATS or generator). The top horizontal segment indicates mains, the middle horizontal segment indicates engine, and the bottom horizontal segment indicates generator. The second digit indicates the measured phase. The top segment indicates 1, the middle horizontal segment indicates 2, and the bottom horizontal segment indicates 3. If only one line is displayed for phase measurement, a phase to neutral measurement is displayed. If two lines are displayed, a phase to phase measure ment is shown. Digits 3-6 indicate what the measured value of the displayed parameter is. The indicators located at the top left of the first four digits of the display indicate the engineering unit of measure to be utilized. The indicators are assigned the following engineering units of measure. o Digit 1: Volts [V] o Digit 2: Frequency [Hz] o Digit 3: Operating Hours [h] o Digit 4: Number of Transfers to Gen. With this information, the example in the figure above reads as follows: Voltage at generator between phase 2 and N is at volts Digit 1: Generator Digit 2: Measurement between phase 2 and N Digits 3 to 6: Numerical value Indicator at digit 4: Voltage [V] Digits 5 and 6 of the display are used to display eight different alarm states. The upper and lower vertical segments are used to indicate the various alarm states. Refer to on page 33 for the description of the alarm messages.

43 Operating Mode AUTOMATIC In the AUTOMATIC operating mode, all engine, GCB, and/or MCB functions are operated via the discrete inputs or automatically by the control unit (i.e. a mains failure). The function of the DTSC-50 depends on the configuration of the unit and how the external signals are used. ED 15, in the upper left corner of the AUTO - MANUA button 3, indicates the automatic operating mode. Detailed operation in automatic mode (mains are present) Preconditions: Generator is stopped ED 12 is not illuminated MCB is closed ED 10 is illuminated Mains are present ED 9 is illuminated Unit is in automatic mode ED 15 is illuminated Start sequence: Action Remote start Discrete input DI3 (remote start) is activated (active HIGH signal) at terminal 18 Operation Engine start relay The engine start relay (relay 2) is energized to engage the starter ED 12 illuminates and ED 13 starts flashing when generator speed has been detected Delay Engine delay time The control unit waits for the engine monitoring delay time configured in the engine parameters (page 55) to expire ED 13 changes to steady illumination after the time expires Delay Generator settling time The MCB will only be opened after this timer has been expired.

The engine will continue to run and the GCB remains closed since Mains is not present! NOTE If mains fails while the Remote start command ( via discrete input 3 ) is still active, the GCB will remain closed, and the engine start signal will still be kept set! The remote start Signal is interpreted by the DTSC-50 as Do not return to the mains source, therefore no transfer actions will take place. Page 44/106 Woodward

45 AMF / Auto Mains Failure Operation The operation sequence for an AMF operation is similar to the above sequence with the difference that a remote start signal is not required for the engine start and the engine monitoring delay time is not considered, i.e. the CBs are operated immediately. For an AMF operation in automatic mode the parameter Emergency power monitoring (page 57) must be configured to ON, no class F alarms may be present, the engine must be ready for operation, and the configured mains fail delay time (page 57) must expire to start the engine. Detailed operation in case of a mains failure : Preconditions: Generator is stopped ED 12 is not illuminated MCB is closed ED 10 is illuminated Mains is present ED 9 is illuminated Unit is in automatic mode ED 15 is illuminated Start sequence: Action Mains failure A mains failure occurred. ED 9 is no longer illuminated Delay Mains fail delay time After the mains failure has been detected, the Mains fail delay timer is triggered. If this timer has expired, the DTSC-50 initiates a start signal to start the Engine. Operation Engine start relay The engine start relay (relay 2) is energized to engage the starter ED 12 illuminates and ED 13 starts flashing when generator speed has been detected Delay Engine delay time The control unit waits for the engine monitoring delay time configured in the engine parameters (page 55) to expire ED 13 changes to steady illumination after the time expires Delay Generator settling time The MCB will only be opened after this timer has been expired.

ED 9 starts flashing Delay Mains settling time After the Mains settling timer has been expired ED 9 is illuminted constantly. The mains is now considered to be stable for a re-transfer. The DTSC-50 provides a special parameter called Bypass mains settling timer on Genset failure that can be configured by the user. If this parameter is configured to YES the Mains settling timer is automatically bypassed if the Mains settling timer is timing and the Genset has failed. If the Bypass mains settling timer parameter is configured to NO, then the Mains settling timer has to expired completely until a re-transfer is being initiated.

47 Generator Circuit Breaker Breaker Closure imits The DTSC-50 has fixed breaker closure limits which prevent the GCB closure if the generator voltage and/or frequency is/are not within these limits. These limits depend on the parameters rated system frequency and rated generator voltage (refer to Measuring on page 53) and cannot be changed. The limits are set as follows: f generator must be within f rated system +/- 10 % Examples: If the rated system frequency is set to 50 Hz, the upper limit is at 55 Hz and the lower limit is at 45 Hz. If the rated system frequency is set to 60 Hz, the upper limit is at 66 Hz and the lower limit is at 54 Hz. V generator must be within V rated generator +/- 10 % Examples: If the rated generator voltage is set to 400 V, the upper limit is at 440 V and the lower limit is at 360 V. If the rated generator voltage is set to 120 V, the upper limit is at 108 V and the lower limit is at 132 V. If the generator voltage and/or frequency is/are not within these limits, the generator ED 12 is flashing and the GCB cannot be closed. If the generator voltage and frequency are within these limits, the generator ED 12 is permanently on and the GCB may be closed. Mains Circuit Breaker The DTSC-50 has flexible breaker closure limits which prevent the MCB closure if the mains voltage and/or frequency is/are not within the mains failure limits. These limits depend on the parameters rated system frequency and rated mains voltage and can be freely configured (refer to Monitoring: Mains Failure imits on page 63 for details). The conditions for closing the MCB are specified as follows and all conditions must be fulfilled: The mains voltage is present. The mains settling time (refer to Emergency Power (AMF) on page 57) has expired. NONE of the following alarms is present: - Mains over/underfrequency - Mains over/undervoltage - Mains rotation field alarm If the mains voltage is present, but the voltage and/or frequency is/are not within these limits, the mains ED 9 is flashing, and the MCB cannot be closed. If the mains voltage and frequency are within these limits, and the mains settling time has expired, the mains ED 9 is illuminated permanently, and the MCB may be closed. The mains ED 9 is off, if the phase-neutral measuring voltage is below 10V. Woodward Page 47/106

48 Functional Description of the 2 nd CB Close Delay Time The DTSC-50 series provides Delayed close GCB and Delayed close MCB signals in the list of configurable parameters (find more details about this under Relay Outputs on page 69) in order to meet the requirements of some special circuit breaker types which require an Enable CB Close signal before the actual CB close signal. The function of these signals is described in the following text. If those CBs are utilized, they require two Close CB signals with a time delay in between from two different relays. This can be achieved by selecting Delayed close GCB (MCB) from the list of configurable parameters for a freely configurable relay (relay 4 or 5). The delay time can be configured with the parameter 2nd GCB (MCB) Close Delay Time. If the user initiates the command Close GCB (MCB), the signal is immediately issued from the fixed relay (relay2 for GCB or relay 1 for MCB) assigned to give the close command. After the configured delay time has expired, the second Close GCB (MCB) signal is issued. The user configures the delay time for the second close command at the relay output. Example for the functionality: Assumption: The close GCB signal is to be issued parallel on a second relay with a delay. Relay 4 shall be used in this example for this. The parameter "Relay 4" has to be configured to "Delayed close GCB" from the list of configurable parameters (refer to Relay Outputs on page 69). The delay time may be configured with the parameter "2nd GCB close delay time"(refer to Application on page 54). A period of 2 seconds shall be configured for this example. If the user triggers the command "Close GCB" now, the following sequence will be performed: The signal "Close GCB" energizes the relay firmly assigned to it (relay 3) immediately. After the configured delay has expired, the signal "Close GCB" energizes the relay assigned by the user (relay 4 in this example) with the configured delay. Signal: close CB t Signal: close CB with delay The delay "t" corresponds with the values of the parameters "2nd GCB close delay time" and "2nd MCB close delay time". If the respective circuit breaker is opened, both relays return to their initial state. NOTE This functionality can only be configured using eopc1. Page 48/106 Woodward

49 Chapter 9. Configuration Restoring Default Values The DTSC-50 can be reset to factory settings easily. This may be comfortable for configuring the DTSC-50 from a known state. NOTE The unit has to be in Operating Mode STOP (page 39) to load the default values. Resetting Via the Front Panel Preconditions for loading the default values: Unit must be in operation mode STOP ED 17 is illuminated The engine must be stopped ED 13 is not illuminated No generator voltage may be present ED 12 is not illuminated Press and hold the UP 7, AARM 2, and STOP 6 buttons simultaneously for at least 10 seconds to reset the values. The factory default values have been restored when all the EDs flash briefly,. Resetting Via eopc1 Precondition for loading the default values: Unit has to be in operation mode STOP ED 17 is illuminated Connect the DTSC-50 with your PC and start eopc1 as described in Configuration Using the PC on page 50.

Configuration Via the Front Panel Operating the control unit via the front panel is explained in Configuring the on page 29. Familiarize yourself with the unit, the buttons meaning/function, and the display monitoring using this section. The display of the parameters via the front panel and the display of the parameters via the computer program eopc1 will differ. NOTE Not all parameters may be accessed or changed when configuring the control unit via the front panel. To properly commission a control unit, eopc1 v3.1xxx or higher and a DPC cable (P/N ) are required. Woodward Page 49/106

50 CAUTION Configuration Using the PC For the configuration of the unit via the PC please use the eopc1 software with the following software version: eopc1 3.1 or higher NOTE Please note that configuration using the direct configuration cable DPC (product number ) is possible starting with revision B of the DPC (first delivered July 2003). If you have an older model please contact our sales department. For configuration of the unit via PC program please proceed as follows: Install the eopc1 program on your notebook/pc according to the provided user manual Consider the options that are given during the installation. Prior to the completion of the installation you will be prompted to select the language with which you want to start the PC program. The language of eopc1 may be changed at any time. The selection of the language refers only to language with which the menus and subprograms that eopc1 program works with. This setting will not change the configured language of the control unit. After the installation of eopc1 has been completed it is necessary to reboot your notebook/pc. Establish a connection between your notebook/pc and the control unit via the DPC cable. Insert the RJ45 plug into the RJ45 port on the control unit (see DPC Direct Configuration Cable on page 25 for details) and the serial cable to the COM1 port of your notebook/pc. You can now start the PC program as follows: - by "Start/Program/Woodward/eoPC1" (version 3.1 or higher) and opening the respective cfg file, or - by a double click on the respective file ending ".cfg" in the subdirectory "/eopc1". The cfg files differ in their language used. Use the file on the enclosed floppy disk with the language you want, i.e. US for US English or DE for German. After the eopc1 program has started, establish communication by pressing the F2 button or selecting Communication -> Connect from the menu. This will establish a data link between the control unit and the notebook/pc. Start the configuration routine pressing the F3 button or selecting Devices -> Parameterize from the menu and adjust the parameter of the unit to your application using this manual. NOTE You find detailed information about eopc1 and the utilization of the software in the user manual belonging to it. NOTE The connection cables delivered with the DPC must be used to connect it to ensure a proper function of the DTSC-50. An extension or utilization of different cable types for the connection between DTSC-50 and DPC may result in a malfunction of the DTSC-50. This may further result in damage to components of the system. If an extension of the data connection line is required, only the serial cable between DPC and notebook/pc may be extended. NOTE Unplug the DPC after configuration to ensure a safe operation! If the DPC remains plugged into the DTSC-50 unit, a safe operation of the unit can not be guaranteed. Page 50/106 Woodward

If the mains drop below or rise above the configured limits the timer will start over. The load transfer from generator back to mains will delayed by this parameter after a emergency power operation. Bypass mains settling timer on Genset fail Netzberuhigungszeit nicht abwarten bei Generator Ausfall Bypass mains settling timer on Genset fail YES/NO Often the Mains settling timer in applications is configured to for example 30 Minutes to ensure that the mains is really in a good condition before a re-transfer is initiated. It could happen, that the mains returns while the Mains settling timer is triggered and the Engine/Genset fails. Usually the full mains settling time needs to be awaited until any further actions are triggered. In many ATS applications it is NOT wished to wait the full Mains settling time in such a situation, because the oad is not supplied by any source in that case. With parameter Bypass mains settling timer on Genset fail the behavior of the DTSC-50 can be selected. 1.) Bypass mains settling timer on Genset fail configured to Yes : The Mains settling timer is automatically bypassed if the Genset fails while the Mains settling timer is timing. 2.) Bypass mains settling timer on Genset fail configured to No : The full Mains settling time needs to expire before a re-transfer to the mains source is initiated. Woodward Page 57/106

76 Chapter 11. Interfaces and Protocols Service Port (RS-232/USB) Interfaces The Woodward specific service port can be used to extend the interfaces of the controller. In conjunction with the direct configuration cable the service port allows service access for configuring the unit and visualize measured data. NOTE The service port can be only used in combination with an optional Woodward direct configuration cable (DPC), which inclucdes a converter box to provide either an USB or a RS-232 interface. Please refer to Chapter Interfaces on page 25. Modbus RTU Slave Protocols Modbus is a serial communications protocol published by Modicon in 1979 for use with its programmable logic controllers (PCs). It has become a de facto standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. The DTSC supports a Modbus RTU Slave module. This means that a Master node needs to poll the DTSC slave node. Modbus RTU can also be multidropped, or in other words, multiple Slave devices can exist on one Modbus RTU network, assuming that the serial interface is a RS-232. Detailed Information about the Modbus protocol are available on the following website: There are also various tools available on the internet. We recommend to use ModScan32 which is a Windows application designed to operate as a Modbus Master device for accessing data points in a connected Modbus Slave device. It is designed primarily as a testing device for verification of correct protocol operation in new or existing systems. It is possible to download a trial version from the following website: Page 76/106 Woodward

77 Modbus Addressing and Data Model The DTSC Modbus slave module distinguishes between visualization data and configuration & remote control data. The different data is accessible over a split address range and may be read via the "Read Holding Register" function. Furthermore, DTSC parameters and remote control data can be written with the "Preset Single Registers" function or "Preset Multiple Registers" (refer to figure below). Modicon address DTSC visualization data Modbus commands: Read Holding Register (0x03) DTSC remote control & configuration data Read Holding (0x03) Preset Multiple Registers (0x10) Preset Single Register (0x06) NOTE All addresses in this document comply with the Modicon address convention. Some PCs or PC programs use different address conventions depending on their implementation. Then the address must be increased and the leading 4 may be omitted. Please refer to your PC or program manual for more information. This determines the address sent over the bus in the Modbus telegram. The Modbus starting address of the visualization data may become bus address for example. Visualization The visualization over Modbus is provided in a very fast data protocol where important system data like alarm states, AC measurement data, switch states and various other information may be polled. According to the DTSC Modbus addressing range, the visualization protocol can be reached on addresses starting at On this address range it is possible to do block reads from 1 up to 128 Modbus registers at a time. Modbus Read Description Multiplier Units Addresses Protocol-ID Gen. voltage 1-N 0.1 V Battery voltage 0.1 V Table 11-1: Modbus - address range block read NOTE Table 11-1 is only an excerpt of the data protocol. It conforms to the data protocol, that is also used by CAN bus. Refer to Data Protocol 4730 on page 79 for the complete protocol. Woodward Page 77/106

78 The following exemplary ModScan32 screenshot shows the configurations made to read the visualization protocol with a block read of 128 registers. Figure 11-1: Modbus - visualization configurations Page 78/106 Woodward

84 Chapter 12. Event ogger The event logger is a FIFO (First In/First Out) memory for logging alarm events and operation states of the unit. The capacity of the event logger is 15 entries. Additional event messages overwrite the oldest messages. Since the DTSC-50 units do not include a clock module, the operating hours are stored with each event logger entry as the timestamp. The individual alarm messages, which are stored in the event history, are described in detail under Alarm Messages on page 33. The operation states, which are stored in the event history, are listed in Table 12-1 on page 85. NOTE The event logger cannot be read out directly from the front of the unit. It can only be read out using the program GetEventog, which can either be used as a stand alone or within eopc1. Installing GetEventog GetEventog Software GetEventog can either be used as a stand alone or within eopc1. In order to call it up from eopc1, it must be installed into the eopc1 installation path. To install GetEventog, start GetEventog_vxxxxx.exe from the GetEventog directory on the CD delivered with the unit. If you want to use GetEventog from inside eopc1, it must be installed into the eopc1 installation directory. Starting GetEventog Connect the DTSC-50 to a free COM port on your computer using the DPC as described under Configuration Using the PC on page 50. Start GetEventog directly or call it up by selecting GetEventog from the menu Tools in eopc1. After starting GetEventog for the first time, you must configure the communication settings. To do this, select the Interface tab, configure the COM port according to the port, to which you have connected the DPC, and enter the other settings as represented in figure Figure 12-1 since these are the default settings of the DTSC-50. Figure 12-1: GetEventog - interface configuration Page 84/106 Woodward

85 Reading Out GetEventog On the Eventlog tab of GetEventog, click the Request Eventlog button to read out the content of the event logger memory. The content of the event logger is displayed as shown in Figure The 15 latest events are displayed in chronological order and each entry is composed like this: "sign";"operating hour";"alarm/state" Figure 12-2: GetEventog - event logger content whereas "sign""+" indicates the occurrence and "-" indicates the disappearance or acknowledgement of the alarm or state "operating hour" serves as a timestamp and indicates the operating hour of the event occurred "alarm/state" indicates the type of alarm or change of state that occurred The alarm codes are the same as displayed on the unit and described under Alarm Messages on page 33. The codes for the operation states are indicated in Table 12-1 below. Example: The entry "+";" h";"00031A" means that alarm 31A unintended stop "00031A" occurred "+" at operating hour 8.4 " h". The operating hours are indicated in decimals, i.e. 8.4 hours are 8 hours and 24 minutes. Number Operation state DTSC Mode: Automatic 71 Mode: Stop 72 Mode: Manual 73 GCB closed 74 GCB opened 75 MCB closed 76 MCB opened 77 Mains not in range 78 Emergency mode active 79 Engine run Table 12-1: Event logger - operation states Storing Event ogger Data Using the Save Eventlog button on the Eventlog tab, you are able to save the content of the event logger in CSV format (comma separated values). Resetting the Event ogger The event logger can only be reset using eopc1. To do this, perform the following steps: Connect the DTSC-50 with your PC and start eopc1 as described in Configuration Using the PC on page 50. Set the parameter Factory settings to YES. Set the parameter Clear Even og to YES. The event logger should be cleared. Woodward Page 85/106
